Sheared helical turbulence and the helicity constraint in large-scale dynamos
A. Bigazzi, A. Brandenburg, K. Subramanian
The effect of shear on the growth of large scale magnetic fields in helical turbulence is investigated. The resulting large-scale magnetic field is also helical and continues to ev…
A radio and optical study of Molonglo radio sources
C. H. Ishwara-Chandra, D. J. Saikia, P. J. McCarthy +1
We present multi-wavelength radio observations with the Very Large Array and narrow- and broad-band optical observations with the 2.5m telescope at the Las Campanas Observatory, of…
ATCA search for 21 cm emission from a candidate damped Ly- absorber at z = 0.101
Nissim Kanekar, Jayaram N Chengalur, Ravi Subrahmanyan +1
We report a deep search for 21 cm emission/absorption from the candidate damped Lyman- system towards PKS 0439-433, using the Australia Telescope Compact Array (A…
Synthesis of Small and Large scale Dynamos
Kandaswamy Subramanian
Using a closure model for the evolution of magnetic correlations, we uncover an interesting plausible saturated state of the small-scale fluctuation dynamo (SSD) and a novel anolog…
Cosmic Microwave Background Polarization Signals from Tangled Magnetic Fields
T. R. Seshadri, Kandaswamy Subramanian
Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface (LSS) of the cosmic microwave background radiation (CMBR).…
Implications of 21cm observations for damped Ly- systems
Jayaram N Chengalur, Nissim Kanekar
We present Giant Metrewave Radio Telescope HI 21cm absorption observations, of candidate and confirmed damped Lyman- systems (DLAS). The derived spin temperatures (T_s) are in a…
